conforming to ISO9001
Application
Sentinel X200 is a non-acid product that has been
formulated for the treatment of ‘kettling’ in hydronic
heating boilers caused by limescale. Unlike
alternative treatments, Sentinel X200 is added to the
system and left there without causing any problems.
Sentinel X200 is extremely successful in reducing
noise problems caused by the presence of limescale
on the heat exchanger surface, and restoring boiler
efficiency. Many noise problems are caused by
system design or mechanical faults. It is important to
check for these before seeking a chemical solution.
Boiler noise can also be caused by sludge (e.g., iron
oxide corrosion debris), in which case, the system
should be cleansed with Sentinel X400.
Dosing & Feeding
1 quart of Sentinel X200 is sufficient to treat a typical
residential system of 25 gallons. Larger systems
should be dosed at 1% of system water. The time
taken for boiler noise to reduce or be entirely
eliminated will depend on the hardness and quantity
of limescale present.
In severe cases, a further dose of Sentinel X200 may
be necessary. Sentinel X200 should be left in the
system. The system water should also be treated
with Sentinel X100 inhibitor, or Sentinel X500
inhibited antifreeze.
Open Systems: Dose via F&E cistern, via a by-pass
feeder or use a dosing vessel.
Sealed Systems: If the system is empty, add to any
convenient point before filling. If full, use a dosing
vessel to inject via the filling loop or other access
point.
